MICRO SMD LIGHT SENSITIVITY
Exposing the micro SMD device to direct sunlight will cause
misoperation of the device. Light sources such as halogen
lamps can effect electrical performance if brought near to the
device.
The wavelengths which have most detrimental effect are reds
and infra-reds, which means that the fluorescent lighting used
10
inside most buildings has very little effect on performance. A
micro SMD test board was brought to within 1cm of a fluo-
rescent desk lamp and the effect on the regulated output
voltage was negligible, showing a deviation of less than 0.1%
from nominal.
